[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] like Figures 1-3 The present embodiment proposes a mobile manhole cover removal device, including a rod body 1 and a roller 2, the roller 2 passes through the side of the rod body 1, an adjusting rod 3 is provided on the top of the rod body 1, a handle 4 passes through the side of the adjusting rod 3, and an adjusting mechanism 5 is provided inside the rod body 1; the adjusting mechanism 5 includes a groove 51, the groove 51 is opened inside the rod body 1, a rectangular groove 52 is opened on the inner wall of the groove 51, a spring 53 is fixedly connected to the inner wall of the rectangular groove 52, and an end of the spring 53 away from the inner wall of the rectangular groove 52 is fixedly connected to an action plate 54, a latch 55 is fixedly connected to the side of the action plate 54, and an action block 56 is fixedly connected to the bottom of the adjusting rod 3.

[0029] A circular shaft 57 passes through the side of the rod body 1, and a slot 58 is provided on the circumferential surface of the circular shaft 57. A force spring 59 is fixedly connected to the inner wall of the slot 58, and an end of the force spring 59 away from the inner wall of the slot 58 is fixedly connected to a baffle 510. A swivel 511 is provided on the circumferential surface of the circular shaft 57. This design is conducive to the baffle 510 being retracted into the interior of the slot 58 through the force spring 59 when the baffle 510 is subjected to force.

[0030] There are two springs 53, which are linearly arrayed on the inner wall of the rectangular groove 52. The initial state of the spring 53 is set to a relaxed state. This design is conducive to engaging with the latch 55 when the action block 56 is pulled, so that the latch 55 is forced to retract to the inner wall of the rectangular groove 52 through the action plate 54 using the elastic force of the spring 53.

[0031] In this embodiment, first, when the staff needs to take out the manhole cover, the staff needs to select the appropriate T-shaped opener 7 according to the model of the manhole cover, and install the T-shaped opener 7 to the top of the rod body 1. After the T-shaped opener 7 is installed, the staff pushes the body to the front of the manhole cover through the roller 2 for positioning, thereby taking out the manhole cover through the principle of leverage. If the staff has little strength and cannot take out the manhole cover smoothly, the staff pulls the adjusting rod 3 through the handle 4, so that the action block 56 at the bottom of the adjusting rod 3 is forced to lift upward. When the action block 56 is lifted upward, the arc surface at one end of the action block 56 engages with the latch 55 on the side of the action plate 54, forcing the latch 55 to be retracted into the rectangular groove 5 by the action plate 54. 2, when the adjusting rod 3 is extended to the length required by the staff, the staff stops pulling the adjusting rod 3. At this time, the arc surface of one end of the action block 56 is stuck in the side of the latch tooth 55, which increases the length of the adjusting rod 3, so that the staff can easily take out the manhole cover through the body. When the staff needs to retract the adjusting rod 3, by pulling the swivel 511, the swivel 511 moves toward the outside of the rod body 1, driving the circular shaft 57 to move accordingly, so that the blocking plate 510 is squeezed and retracted into the inside of the card slot 58 through the force spring 59, so that the action block 56 is retracted into the inside of the rectangular groove 52 by the spring 53, and the latch tooth 55 is no longer engaged with the action block 56, so that the adjusting rod 3 is retracted into the inside of the rod body 1, achieving an adjustable effect. Example

[0032] like Figures 3-6 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a lubrication device 6 is provided inside the rod body 1, and the lubrication device 6 includes a force-bearing rod 61, and the force-bearing rod 61 is fixedly connected to the side of the action plate 54. The side of the force-bearing rod 61 is fixedly connected to a movable plate 62. Such a design is conducive to driving the force-bearing rod 61 to move when the action plate 54 moves.

[0033] An oil bag 63 is provided on the inner wall of the groove 51 , and a nozzle 64 is provided on the side of the oil bag 63 . The inner wall of the groove 51 is fixedly connected to a limiting plate 65 . This design is beneficial for the lubricating oil to be sprayed out through the nozzle 64 when the inside of the oil bag 63 is squeezed.

[0034] The side cross-section of the force-bearing rod 61 is configured to be L-shaped, and the limiting plate 65 is located on the side of the movable plate 62 . This design is conducive to the limiting plate 65 being able to limit the movable plate 62 .

[0035] The action block 56 is set to be L-shaped, and one end of the action block 56 is set to be an arc surface. The arc surface of the action block 56 is engaged with the latch tooth 55. This design is beneficial when the action block 56 is pulled. The arc surface at one end of the action block 56 is lifted upward through the latch tooth 55 and can be stuck on the latch tooth 55.

[0036] The slot 58 is located on the side of the swivel 511 , and the swivel 511 is configured to be special-shaped. This design facilitates the staff to pull out the swivel 511 under force, so that the adjusting rod 3 is retracted into the rod body 1 .

[0037] The blocking plate 510 is elastically connected to the inner wall of the slot 58 via the force spring 59 . This design is advantageous in that when the blocking plate 510 is subjected to force, the blocking plate 510 is retracted into the slot 58 via the force spring 59 .

[0038] There are two rollers 2, which are symmetrical to each other along the vertical central axis of the bottom of the rod body 1. A T-shaped opener is provided on the top of the rod body. This design is conducive to the staff replacing the T-shaped opener 7 according to the models of different manhole covers, and is convenient for the staff to load and unload the T-shaped opener 7.

[0039] In this embodiment, in the adjustment mechanism 5, when the adjustment mechanism 5 is working normally, rust may be generated during the process of the engagement between the latch tooth 55 and the action block 56, resulting in the assembly not being able to operate normally. When the staff pulls the adjustment rod 3 or pulls the swivel 511, the force-bearing rod 59 fixed on the side of the action plate 54 is forced to move, causing the movable plate 62 to slide on the inner wall of the groove 51, thereby squeezing the oil bag 63, causing the interior of the oil bag 63 to be squeezed, and the lubricating oil is sprayed through the nozzle 64 to the engagement between the latch tooth 55 and the action block 56, so that the engagement between the latch tooth 55 and the action block 56 can complete the work normally. The limiting plate 65 fixed on the inner wall of the groove 51 limits the oil bag 63 and the movable plate 62, so that the lubrication device 6 can complete the work flexibly and quickly, thereby improving the work efficiency of the staff.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
